A Master Reset forces a Nextel phone to refresh it's network settings. This is useful whenever Nextel has reconfigured your phone, particulary when you've switched from a Private IP (the default) to a Public IP (required by Ranger Mobile Application).

To perform a Master Reset:

1. On the phone, press the “red hangup” button twice to return to home screen of the phone.
2. Press the Menu key.
3. Scroll to Settings and press OK key. Note that Settings might be on Page 2, and if so, you need to press More to see it.
4. Scroll to Advanced and press the OK key.
5. Scroll to Connectivity and press the OK key.
6. Scroll to Master Reset and press the OK key.
7. Enter “000000” (six zeroes) for the Security Code and choose OK.
8. Press YES to confirm.
9. Press the OK key if warned to “see manual”. The phone will turn itself off.
10. Wait 60 seconds, then turn the phone back on. The phone will power up.
11. If the phone prompts to “update your browser info,” choose OK.

“Packet data” service allows connections from the phone to the Internet.

Some phones might not “see” the packet data service unless the Name and Lines fields are filled out on the My Info screen. To check for this issue:

1. On the phone, press the “red hangup” button until you get to the home screen of the phone.
2. Press the Menu key.
3. Scroll to “My Info” and press the OK key. Note that My Info might be on Page 2, and if so, you need to press More to see it.
4. Scroll to the “Name” field. If it is blank, enter your name in it.
5. Scroll to the “Line1” field. If it is blank, enter your phone number in it.
6. Scroll to the “Line2” field. If it is blank, enter your phone number in it.

Each phone must have the proper Nextel service plan in order to use the Ranger Mobile Application. Specifically, the phone must be setup with “packet data with public IP.”

Before installing the Mobile Application, check the phone IP address and optionally check the configuration of packet data

To enable these services, call you Nextel representative and tell them to add “packet data with public IP” to all phones you intend to install the Ranger Mobile Application on. Note that as of June 2008, “packet data with public IP” is $12.99/month ($9.99 for packet data and $3.00 for public IP) per phone.

“Public IP” service allows an Internet-based service, such as Ranger, to push data to the phone.

To determine the IP Address of a phone:

1. On the phone, press the “red hangup” button until you get to the home screen of the phone.
2. Press the Menu key.
3. Scroll to “My Info” and press the OK key. Note that My Info might be on Page 2, and if so, you need to press More to see it.
4. Scroll down to the Carrier IP section. The Carrier IP is the IP Address of the phone.

If the IP Address starts with “10.” or “192.168.”, the phone DOES NOT have a Public IP. Call Nextel immediately to update your service plan. Ask them for “packet data with public IP.”

If the IP begins with something else, you have a Public IP.
